The aggressive infestation that took hold in the Matanuska-Susitna Borough north of Anchorage in 2016 has now spread north, covering hillsides in the communities outside the park with rustred dead trees and reaching into park boundaries.

The southern resident killer whales who returned to their traditional summer feeding grounds in the Salish Sea on Tuesday and Wednesday after a long absence have apparently left again, and although most of the members of J-, K- and L-Pods appeared to be healthy, at least one may be close to starvation.

Local fisherman Darren Porter saw this coming. "It's just common sense. I mean, you can’t take your fishbowl and put it on your stove.”

This season is shaping up to be the worst fall for salmon fishing on the Yukon River in recorded history. It follows the worst recorded summer salmon season ever.

New data show the population of baby lobsters off New England is below average, raising concerns about the size of future commercial hauls of the valuable crustaceans as waters warm.

The lobster population along the Norwegian coast is much worse off than first thought. New research shows a huge decline.

Summer commercial Dungeness crabbing was well below average in Lynn Canal, with fishermen hauling in an estimated 105,000 pounds this year compared

In the wake significant caribou wastage late last month along the Tibbitt to Contwoyto winter road, there is another instance of what appears to be wastage related to ptarmigan. Yellowknife resident Brad Olson shared a social media post earlier this month showing what appears to be almost two dozen birds killed and left to rot.

On the Yukon River, subsistence salmon fishing is being closed to protect king salmon as they migrate upriver.

Since the initial June to July heatwave shocked the Pacific Northwest, Heim says the Tsolum River Restoration Society has observed significantly fewer fish in the river, especially in its lower portions. Many of the remaining coho, which survived the heat wave, are suffering from diseases and fin rot as a result of heat stress.

They are brightly coloured, beautiful and hungry — tropical fish and sea urchins are thriving in southern waters warmed by climate change. But now they are devastating kelp forests already knocked around by marine heatwaves.   

It's not the first time snow geese have died in large numbers in western Nunavut. The cause of this event is under investigation, but overpopulation could have played a role, says the Canadian Wildlife Service.

Thirteen of the state's 14 confirmed mammal deaths have occurred in the past month.

Late last month, the carcasses of a dozen or more caribou were found along the Tibbitt to Contwoyto winter road by someone who said the slaughter and wastage was an act of disrespect and greed.
